Procedure

4-({4-[(dimethylphosphoryl)methyl]piperazin-1-yl}methyl)-5-(trifluoromethyl)aniline (yellow solid, 3.66 mmole, 1.0 eq.) was dissolved in 15 mL anhydrous dichloromethane. 3-Iodo-4-methylbenzoyl chloride (1.58 grams, 5.64 mmole, 1.54 eq.) was added in one portion. At 0° C., under N2 protection, diisopropylethyl amine (2.4 mL, 14.0 mmole, 3.8 eq.) was added dropwise in 3 minutes. The reaction mixture was stirred at 0° C. under N2 for 30 minutes. It was then evaporated to remove most of the volatile components. The residue was purified via column chromatography (elution sequence: 100% dichloromethane—1% MeOH/dichloromethane/sat.NH3—10% MeOH/dichloromethane/sat.NH3), 40 mg of light yellow color oil was obtained and identified as the desire iodide. MS (LC/MS): 592.3 [M-].
